Procedure

The title compound was prepared using the procedure as described in Example 20H substituting the product of Example 21A (120 mg, 0.253 mmol) for the product of Example 20G. The crude product was purified by trituration with Et2O/hexanes which resulted in 36 mg (38%) of the title compound as a white solid. 1H NMR (DMSO-d6) δ 9.32 (br s, 1H), 7.75 (m, 4H), 7.60 (s, 1H), 7.55 (d, J=7.8 Hz, 1H), 7.10 (t, J=7.8 Hz, 1H), 6.87 (d, J=7.8 Hz, 1H), 3.05-2.70 (m, 4H), 2.30 (m, 1H), 1.82 (m, 3H), 1.43 (m, 1H); MS (ESI+) m/z 374 (M+H)+.
